Anxiety disorder is a common emotional disorder,with its pathological mechanisms involving the imbalance of multiple neurotransmitter systems,especially the dysfunction of the gamma-aminobutyric acid(GABA)system.This article explored the TCM understanding of anxiety disorder,and summarized and organized the research on the regulation of GABA system in the treatment of anxiety disorders through TCM monomers and formulas from the aspects of terpenes,flavonoids,phenolic acids,lignans,cinnamic acids,saponins,etc.At present,the research mainly involved chrysin,baicalin,ginsenoside,Baihe Dihuang Decoction,Bentun Decoction,Suanzaoren Decoction,Chaihu Jia Longgu Muli Decoction,etc.The mechanism involved regulating the inflammatory response of the body,alleviating oxidative stress damage,restoring the hyperactive HPA axis and other action pathways,which could provide a reference for the related research of TCM anti anxiety treatment and the development of new drugs.

OBJECTIVE To analyze occupational exposure to sharps injuries among medical staff in different posi-tions in a three-A hospital.METHODS A retrospective collection of all sharps injury cases reported from 2018 to 2023 in a general hospital was conducted.The basic characteristics,high-risk links,involved instruments,post-exposure emergency treatment and follow-up situations were analyzed,while sharps injury characteristics of medi-cal staff in different positions were classified and discussed.RESULTS Over six years,340 sharps injuries occurred with the highest incidence among interns(2.70 cases/100 FTE·year)and the lowest among logistics staff(1.05 cases/100 FTE·year).Jun.was the month with the highest incidence,averaging 7.33 cases.High-risk links in-cluded instruments handling,placing instruments into sharp containers and removing needles from rubber or other barriers,accounting for 76.47%.Nurses experienced injuries mostly occurred in general wards and were related to scalp needles;doctors mostly occurred in operating rooms and were due to surgical instruments;interns were pri-marily injured by blood collection needles;pharmacists and medical technicians were related to ampoule handling;while logistical staff were mostly injured by hollow needles and glass fragments from waste disposal.Nurses and doctors were the main injured groups,with a higher incidence among females(25-<35 years)and males(less than five years of work experience).The exposure source was mainly hepatitis B virus(HBV)infection.Post-ex-posure treatment was primarily standardized emergency treatment,but a higher proportion of non-standardized treatment was observed among logistics staff.Follow-up reports showed that interns and logistical staff had lower submission rates and lower training coverage.CONCLUSIONS Significant differences exist in sharps injury charac-teristics among medical staff in different positions.Attention should be paid to position-specific high-risk links and instruments.Targeted training and occupational health management should be strengthened to effectively prevent occupational exposure.

Objective:To investigate the numbers of peripheral blood CD4 +T cell subpopulations in patients with elderly-onset rheumatoid arthritis (EORA) and its clinical significance. Methods:A total of 188 patients with newly diagnosed RA in the department of rheumatology and immunology of the Second Hospital of Shanxi Medical University from January 2020 to December 2023 were collected, including 48 cases of EORA (age of onset: ≥60 years old), 140 cases of young-onset rheumatoid arthritis (YORA) (18 years old ≤ age of onset < 60 years old). Meanwhile, 151 healthy controls (HC) were collected, of which 31 persons aged 60-85 years were included as HC group 1 (HC 1) and 120 individuals aged 18-59 years were included as HC group 2 (HC 2). Peripheral blood CD4 +T lymphocyte subsets of these participants were assessed by flow cytometry. Differences between groups were analyzed using independent-samples t test, Mann-Whitney U test or χ2 test. Results:Compared with healthy individuals, the absolute counts and percentages of peripheral blood Treg cells in patients with EORA were significantly decreased [absolute counts: 32.65 (23.04, 47.73) cells/μl vs. 23.03 (15.28, 32.12) cells/μl, Z=-3.35, P=0.001; percentages: 5.12%(4.13%, 6.16%) vs. 3.72% (2.79%, 4.82%), Z=-4.10, P<0.001], while the Th17/Treg cell ratio was increased [0.16 (0.12, 0.29) vs. 0.26 (0.18, 0.46), Z=-2.94, P=0.003], the differences are all significant. There was a tendency with higher absolute counts and percentages of Treg [absolute counts: 23.03 (15.28, 32.12) cells/μl vs. 20.97 (14.01, 30.64) cells/μl, Z=-0.58, P=0.561; percentages: 3.72%(2.79%, 4.82%) vs. 3.38% (2.39%, 4.71%), Z=-1.06, P=0.287] and lower Th17/Treg ratios [0.26 (0.18, 0.46) vs. 0.27 (0.19, 0.46), Z=-0.32, P=0.751] in EORA when compared to patients with YORA, but no significant differences were observed. Conclusion:Patients with EORA also have the reduced numbers of peripheral blood Treg cells and immune imbalance of Th17/Treg, suggesting that immune imbalance or dysfunction caused by defects in Treg cell counts and/or function contributes to the development of EORA, and that targeting Treg cells may be a promising therapeutic strategy for EORA.

Objective To generalize and summarize the types,content elements,outcome measures,application effects,and safety monitoring of the infant-cued behavior-based feeding,so as to provide guidance for the clinical application and research in the future.Methods The literature was retrieved from PubMed,CINAHL,CNKI,and Wanfang Data-base,with a retrieval timeframe from database establishment to August 20,2024.The included literature was sum-marized and analyzed.Results A total of 28 studies were included,of which 15 were randomized controlled trials,7 were quasi-experimental studies,and 6 were observational studies.The infant-cued behavior-based feeding pattern could be categorized as ad libitum feeding,demand feeding,semi-demand feeding,and behavioral cue-based feeding.The content elements included assessment,supporting strategies,and advancement of oral feeding.The infant-cued behavior-based feeding pattern had a positive impact on feeding and developmental outcomes,immune function,rate of complications and length of hospital stay in preterm infants.The safety monitoring consisted of heart rate,blood oxygen saturation,blood sugar,and daily weight gain.Conclusion It is beneficial to implement the infant-cued behavior-based feeding pattern in preterm infants,which leads to better clinical outcomes.To support its implementation in clinical practice,we need to validate and enhance the application value of the feeding pattern in the future by concentrating on clinically individual differences,refining feeding intervention programs,improving effect evaluation and safety monitoring.

Objective:To investigate the relationship between thoracic aortic calcification (TAC) and autonomic nervous system (ANS) function in patients receiving continuous ambulatory peritoneal dialysis (CAPD).Methods:It was a cross-sectional study. The CAPD patients with dialysis duration >6 months between January and December 2022 were retrospectively enrolled. The baseline clinical data, heart rate variability (HRV) data such as standard deviation of all normal to normal intervals (SDNN), root mean square of successive differences between adjacent normal-to-normal intervals (RMSSD), high frequency (HF), very low frequency (VLF), low frequency (LF), LF/HF, acceleration capacity (AC) and deceleration capacity (DC), and skin sympathetic nerve activity (SKNA) were collected. TAC was defined as TAC score (TACS) >100 AU. The patients were divided into TACS >100 AU group and TACS≤100 AU group based on whether the thoracic aorta was calcified. The differences of those data between the two groups were compared. Logistic regression model was used to analyze the related factors of TAC. Spearman correlation analysis method was used to analyze the correlation between peripheral blood neuropeptide Y, ANS parameters, average amplitude SKNA (aSKNA) and TACS.　Cox regression model was used to analyze the risk factors of all-cause mortality in patients with CAPD.Results:The study included 106 CAPD patients with 50 males (47.2%), age of (46.04±11.10) years and dialysis duration of (41.55±30.52) months. TACS>100 AU group exhibited significantly lower heart rate ( t=2.015, P=0.046), DC ( t=2.131, P=0.035), LF/HF ( Z=3.332, P<0.001) and ln(LF/HF) ( t=3.326, P=0.001), and higher AC ( t=-2.392, P=0.019) than TACS≤100 AU group. Multivariate logistic regression analysis results showed that after adjusting for age and eosinophil count, lnVLF ( OR=0.66, 95% CI 0.45-0.98, P=0.038), lnLF ( OR=0.69, 95% CI 0.49-0.97, P=0.032), DC ( OR=0.79, 95% CI 0.64-0.99, P=0.039) and AC ( OR=1.32, 95% CI 1.04-1.68, P=0.021) were independently correlated with the risk of TAC. Spearman correlation analysis showed that neuropeptide Y level in peripheral blood was correlated with aSKNA ( r=0.23, P=0.017), lnSDNN ( r=-0.20, P=0.036) and TACS ( r=0.19, P=0.048). During the follow-up period of (25.8±4.2) months, 5 patients (4.72%) died, including 1 patient in the TACS≤100 AU group and 4 patients in the TACS>100 AU group. Compared with the survival group, the death group had higher TACS ( Z=-2.262, P=0.024) and lower LF/HF ( Z=-2.750, P=0.006). Cox regression analysis results showed that increased ln(LF/HF) was an independent influencing factor for all-cause mortality in CAPD patients ( HR=0.22, 95% CI 0.05-0.83, P=0.026). Conclusions:HRV parameters (lnVLF, lnLF, AC and DC) of CAPD patients are independently associated with TAC. The dysfunction of ANS in CAPD patients (especially the decreased vagus nerve activity) may promote TAC.

Objective To observe the clinical efficacy of self-prescribed Chaigui Tongmai Formula combined with warm needle moxibustion in treating lower extremity arteriosclerosis obliterans(LEASO)with cold coagulation and blood stasis syndrome.Methods A total of 90 patients diagnosed with LEASO of cold coagulation and blood stasis syndrome who were treated in the outpatient and inpatient departments of the Ulcer and Vascular Disease Department of Cangzhou Hospital of Integrated Traditional Chinese and Western Medicine between November 2022 and November 2023 were selected as study subjects.Patients were randomly divided into an observation group and a control group using a random number table,with 45 cases in each group.Both groups received health education and conventional treatment.The control group was treated with oral administration of self-prescribed Chaigui Tongmai Formula,while the observation group received additional warm needle moxibustion based on the control group's treatment.Both groups were treated for 3 weeks.After treatment,clinical efficacy was evaluated by observing changes in TCM syndrome scores,intermittent claudication distance,ankle-brachial index(ABI),toe-brachial index(TBI),hemodynamic parameters,and serum inflammatory factor levels before and after treatment in both groups.Safety and adverse reactions were also assessed.Results(1)The total effective rate was 95.56％(43/45)in the observation group and 80.00％(36/45)in the control group.The efficacy of the observation group was significantly superior to that of the control group,with a statistically significant difference(P＜0.05).(2)After treatment,TCM syndrome scores and intermittent claudication distance were significantly improved in both groups(P＜0.05),and the improvement in the observation group was significantly greater than that in the control group,with a statistically significant difference(P＜0.05).(3)After treatment,intermittent claudication distance was significantly improved in both groups(P＜0.05),and the improvement in the observation group was significantly greater than that in the control group,with a statistically significant difference(P＜0.05).(4)After treatment,ABI and TBI were significantly improved in both groups(P＜0.05),and the improvement in the observation group was significantly greater than that in the control group,with a statistically significant difference(P＜0.05).(5)After treatment,whole blood low-shear viscosity,high-shear viscosity,and plasma viscosity levels were significantly improved in both groups(P＜0.05),and the improvement in the observation group was significantly greater than that in the control group,with a statistically significant difference(P＜0.05).(6)After treatment,levels of IL-18,hs-CRP,and IC AM-1 were significantly improved in both groups(P＜0.05),and the improvement in the observation group was significantly greater than that in the control group,with a statistically significant difference(P＜0.05).(7)During treatment,the incidence of adverse reactions was 4.44％(2/45)in the observation group and 6.66％(3/45)in the control group.There was no statistically significant difference in the incidence of adverse reactions between the two groups(P＞0.05).Conclusion Self-prescribed Chaigui Tongmai Formula combined with warm needle moxibustion significantly promotes the recovery of clinical symptoms,reduces inflammatory responses,improves hemodynamic parameters,and enhances the quality of life in patients with LEASO of cold coagulation and blood stasis syndrome,demonstrating notable efficacy and good safety.

Objective To explore the clinical efficacy and safety of immediate laparoscopic radical prostatectomy immediately following the diagnosis of locally advanced prostate cancer.Methods A retrospective analysis was performed for 63 patients with locally advanced prostate cancer who met the inclusion criteria diagnosed in The 1st People's Hospital of Qujing City,Yunnan Province from January 2018 to January 2023.All patients were diagnosed via ultrasound-guided transperineal prostate biopsy.The experimental group consisted of 37 patients who underwent immediate laparoscopic radical prostatectomy after pathological diagnosis,followed by postoperative adjuvant hormone therapy.The control group included 26 patients who first received 3 months of neoadjuvant hormone therapy before undergoing radical surgery,followed by adjuvant hormone therapy postoperatively.The two groups were compared in terms of surgical duration,intraoperative blood loss,length of hospital stay,duration of catheterization,positive surgical margin rate,rectal injury,positive lymph node rate,incidence of urinary fistula and lymphatic leakage,changes in PSA level,postoperative urinary control,biochemical recurrence and distant metastasis.Results In the control group,serum PSA levels,prostate volume,and clinical staging significantly decreased after neoadjuvant hormon therapy.The positive surgical margin rate in the experimental group was significantly higher than that in the control group,with a statistically significant difference(P<0.05).There were no statistically significant differences between the two groups in terms of surgical duration,intraoperative blood loss,length of hospital stay,duration of catheterization,rectal injury,positive lymph node rate,incidence of urinary fistula and lymphatic leakage(P>0.05).Follow-up at 18 to 36 months revealed no statistically significant differences between the two groups in terms of serum PSA levels at one month post-surgery,complete urinary control rate at six months post-surgery,and biochemical recurrence and distant metastasis at one and two years post-surgery(P>0.05).Conclusion Immediate laparoscopic radical prostatectomy following the diagnosis of locally advanced prostate cancer is a clinically safe and feasible treatment option.Noadjuvant hormone therapy reduces tumor staging,lowers the positive surgical margin rate,significantly decreases prostate volume,and provides greater operational space without increasing surgical risks.

Objective To evaluate the efficacy of complete pelvic floor peritoneal reconstruction in reducing postoperative ileus incidence and accelerating recovery following laparoscopic radical cystectomy with orthotopic neobladder construction.Methods A retrospective study was conducted to select 62 patients who underwent the operation in Qujing Hospital Affiliated to Kunming Medical University from January 2017 to September 2024.According to whether complete pelvic floor peritoneal reconstruction was performed during the operation,they were divided into the conventional group(n=25)and the reconstruction group(n=37).Postoperative ileus rates and recovery parameters were compared to assess the clinical value of complete pelvic floor peritoneal reconstruction.Results The reconstruction group showed better postoperative recovery compared to the routine group:gastrointestinal function recovery time[3(2,4)d vs 4(3,5)d,P=0.032],abdominal drainage time[12(10,13.5)d vs 14(12,15)d,P=0.006],pelvic drainage time[12(9,13.5)d vs 14(11,16)d,P=0.015],postoperative hospital stay[18(15.5,26)d vs 25(17,30.5)d,P=0.016],and hospital expenses[(53,695.67±10,182.43)yuan vs(60,803.73±14,449.24)yuan,P=0.027].Postoperative nutritional markers,including total protein[(64.49±6.82)g/L vs.(61.56±4.03)g/L,P=0.038]and albumin[(36.08±5.29)g/L vs.(33.40±3.57)g/L,P=0.020],were higher in the reconstruction group.No significant difference was found in ileus incidence(44.00%vs.32.43%,P=0.355).Other parameters—baseline characteristics,postoperative globulin and prealbumin levels,gastric tube retention,stent/catheter removal time,and complications(anastomotic leakage,urinary fistula,wound infection)—showed no intergroup differences(P>0.05).Conclusion The application of complete pelvic floor peritoneal reconstruction technique in laparoscopic radical cystectomy with orthotonic neobladder provides better protection for the intestine,reduces surgical area adhesions,promotes gastrointestinal function recovery,shortens abdominal and pelvic drainage times,accelerates patient rehabilitation,reduces hospital stay and expenses.However,whether it can effectively reduce postoperative intestinal obstruction rates still requires more data and experimental verification.

Objective : To explore the utility of a nomogram integrating contrast-enhanced CT radiomics with clinical features in the preoperative prediction of WHO/ISUP grade for clear cell renal cell carcinoma(ccRCC). Methods: A total of 214 patients with pathologically proven ccRCC who underwent enhanced CT scan before surgery were retrospectively included. According to the WHO/ISUP grade system, the cases were classified into low-grade(grades Ⅰ-Ⅱ) and high-grade(grades Ⅲ-Ⅳ), and then randomly divided into training and test set with a ratio of 4 ∶1. Regions of interest were segmented from both unenhanced and three-phase enhanced images, and radiomic features were extracted. Feature selection and dimensionality reduction were performed using Spearman rank correlation coefficients and LASSO regression, followed by the construction of the radiomic model with the KNN algorithm. Clinical and semantic imaging features were selected through univariate and multivariate analyses, and a clinical model was developed using the KNN algorithm. The clinical and radiomics signatures were used to construct a combined model and a nomogram was developed. The ROC curve and delong test were used to evaluate the diagnostic performance of the model, while calibration and decision curve analyses assessed its accuracy and clinical applicability. Results: 8 clinical features and 11 radiomic features were selected. The combined model, integrating these clinical and radiomics signatures, exhibited robust predictive performance with AUC values of 0.887 in the training set and 0.800 in the test set. The calibration curve demonstrated good consistency between the nomogram model and actual outcomes, while decision curve analysis indicated a favorable net benefit for the nomogram. Conclusion The nomogram constructed by combining radiomics and clinical signatures can provide evidence for preoperative prediction of ccRCC grade and guide clinical decision-making.

Objective To analyze the clinical characteristics,laboratory test,imaging examination,and treatment outcome of invasive Klebsiella pneumoniae liver abscess syndrome(IKPLAS)in the elderly,and improve clinicians' understanding on this disease.Methods Clinical data of 7 elderly patients who were diagnosed with IKPLAS in a hospital from January 2020 to February 2024 were analyzed retrospectively.Results Among the 7 elderly patients with IKPLAS,there were 3 males and 4 females,ranging in age from 60 to 78 years old.All 7 patients were with community-acquired infection.The main clinical symptoms were fever(n=7),chills(n=6),upper abdominal pain(n=4),fatigue and poor appetite(n=3),cough and expectoration(n=5),vomiting(n=3),vision decrease(n=2),and disturbance of consciousness(n=1).All 7 patients had pathogenic evidence of Klebsiella pneumoniae(KP),including 4 cases with KP isolated from liver puncture pus,3 from blood culture,and 1 from both liver puncture pus and intraocular pus.Among the 7 patients,there were 5,2,1,3,1,1 cases combined with pulmonary abscess,endophthalmitis,brain abscess,bloodstream infection,urinary system infection,and pelvic infection,re-spectively.Conclusion Elderly patients with IKPLAS have a variety of underlying diseases and diverse clinical symptoms,showing no specificity.Once IKPLAS was suspected,timely testing for pathogen and screening for other metastatic infection sites outside the liver should be performed.Timely drainage of liver abscess and selection of ap-propriate antimicrobial agents for treatment based on antimicrobial susceptibility testing result can improve patients' survival rate.
